It's not pussy defense, it's good defense. If the defender is in position and the offensive player tries to create space it's a foul. Other teams do the same thing it means they are well coached. I mean you said yourself the UK player tried to create space with his arm, that is an offensive foul no matter what.
At the top of the key? As Calipari pointed out, do that crap in the NBA and they'll fine you for it now. It's a BS way to play the game. Oh, your arm has knocked me down. I'll act like I'm fainting.
